0G DA (Data Availability) gRPC is one of 9 APIs that [0G Labs](https://apis.io/providers/0g-labs/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Data Availability, Blockchain, Web3, gRPC, and Crypto Infrastructure. The published artifact set on APIs.io includes API documentation.

gRPC surface for the 0G data-availability layer. The Disperser service accepts blobs asynchronously (DisperseBlob), exposes polling for processing state (GetBlobStatus) and retrieval of a previously dispersed blob (RetrieveBlob); the Retriever service reads blobs back from the DA nodes; and the node-side Signer service handles BatchSign, BatchRetrieve and GetStatus. Rollups settle against this layer — OP Stack, Arbitrum Nitro, EigenLayer AVS and Babylon AVS integrations are all documented.
